ESP32-C3-DevBoard: common questions

What microcontroller does the ESP32-C3-DevBoard use?

The ESP32-C3-DevBoard is built around the ESP32-C3-WROOM-02, from the ESP32 family.

How big is the ESP32-C3-DevBoard PCB?

The ESP32-C3-DevBoard measures 25.4 × 26 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-C3-DevBoard?

15 components, from 11 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the ESP32-C3-DevBoard design files?

From the 21km43/ESP32-C3-DevBoard repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the ESP32-C3-DevBoard design in my own project?

The repository has no license, so all rights stay with 21km43. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ESP32-C3-DevBoard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
